Modified Lee bottom dump

I am new to casting have been loading for 60 years,never too late to start a new project.I purchased my molds and a Lee 20# bottom dump pot. Just had a total shoulder replacement so I couldn't use the pot without modifying it I made a push button leaver to open the metering rod. It works great good control instant shutoff no dripping. I .used the knob that came with the pot simply taped a 1/4 20 thread and screwed it to the metering rod.this puts the weight center on the rod for better function (see pic),the meter is a furnace anilizer seems 800^ seems to cast the best for me.any comments would be appreciated thanks.            Rounder 45
